This app is provided on behalf of the Swiss Federal Railways SBB.

It is part of an SBB service for process-based coordination of movements of people during maintenance work in complex tunnel structures. It can only be used by SBB employees and employees of contracted companies as part of the cooperation within SBB-led operations. The use of the app requires activation by authorized SBB employees.

Depending on their role, the app provides employees with different, sometimes map-based, overviews of the current status of their teams, as well as various functions for controlling or logging person movements and increasing personal safety.

The "Location Infrastructure" app takes care of the necessary location of the staff during the assignment.
